I just received my new Asus A7V600 motherboard that will upgrade from my old A7A266 motherboard. I have an Athlon XP 1600+ processor and one stick of 256 MB DDR 2100 RAM. I put these components and my video card on the new A7V600 motherboard and plugged in the power supply. The light on the motherboard came on just fine. I hit the power switch on the front and the CD light blinked and the fans inside started spinning. About three seconds after the fans started spinning and the hard drive just starts making noise, the fans lose power and come to a stop. The motherboard light stays lit the whole time, but the rest of the computer just stops. Could this be a voltage issue? Or maybe a compatibility issue? I checked the ASUS and AMD websites, and these two products are supposed to work together. Any suggestions? Thanks!
